Link C3850 to Dell 8132F Using SFP Interconnect (copper)

[dennis]

I am introducing new Cisco C3850 switches into an existing Dell environment. This will be a phased replacement so I have a need to link the 3850's to Dell 8132F's. My 3850's each have a C3850-NM-4-10G network module and the Dell switches have SFP+ ports. So the plan is to link the switches using 10GB links. I would like to use the copper SFP+ interconnect cables. But the distance between the switches require a 10 meter cable (SFP-H10GB-ACU10M). But the 3850 specs only list the 5 meter (SFP-H10GB-CU5M) cable as supported.

So I have two questions. First is if the 10 meter cable will work and second has anyone run into any issues linking the 3850's to Dell switches via 10GB.

I think I answered my first question. Doing a bit more digging I found the "Cisco 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix" which shows the SFP-H10GB-ACU10M is supported on the 3850 with OS XE 3.6.0E installed.

Still would like to know of anyone linking the 3850 to the 8132F however...

Has not done it, but should not be an issue as long as you are only connecting the 2 switches using one link, so there is STP incompatibility to worry about.
